etc. This is despite adding libgfortran.spec.in to libgfortran and
it generating the expected libgfortran.spec during the build. I assume
that libtool itself need to be patched to solve this. Also, since libquad
is being added to the FSF gcc tree, it would be nice to have a configure
option for building libgfortran against the static libquad thus eliminating
any need to pass -lquad through libgfortran.spec at all.
